Abstract

We propose a novel grating in a nematic liquid crystal cell with an azo polymer surface (APS). In this system, the polarization grating inscribed on APS modulates the liquid crystal director. The grating effect can be enhanced or reduced by polarization switching of only one pump beam due to strong polarization sensitivity of azobenzene chromophores.
